Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF6-18DP-3.5DSA(05) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (18)
• Number of rows (2)
• Pitch - mating (0.138" / 3.50mm)
• Row spacing - mating (0.197" / 5.00mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Latch Holder)
• Operating temperature range (-30°C ~ 85°C)
• Voltage rating (300V)
• Material flammability rating (UL94 V-0)

The MDF6-18DP-3.5DSA(23) meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete MDF6-18DP-3.5DSA(05).

Parameter Comparison

Engineering Selection Recommendations

The MDF6-18DP-3.5DSA(23) is the direct substitute for the obsolete MDF6-18DP-3.5DSA(05). Both connectors share identical mechanical and electrical specifications across all critical parameters. The primary distinction is product status: the MDF6-18DP-3.5DSA(05) is obsolete, while the MDF6-18DP-3.5DSA(23) is active and currently in production.

Both parts maintain RoHS compliance and carry identical certifications (UL94 V-0, EAR99, HTSUS 8536.69.4040). The MDF6-18DP-3.5DSA(23) carries ROHS3 compliance, representing an updated regulatory classification. Contact finish specifications differ slightly (Tin-Copper versus Tin on the mating surface), but both finishes are functionally equivalent for the specified voltage and temperature operating ranges.

For new designs or ongoing procurement, the MDF6-18DP-3.5DSA(23) is the appropriate selection due to its active product status and current availability.

Frequently Asked Questions (FAQ)

Q: Can the MDF6-18DP-3.5DSA(23) be used as a direct replacement for the MDF6-18DP-3.5DSA(05)?

A: Yes. Both connectors are mechanically and electrically identical across all critical parameters: 18 positions, 2 rows, 3.5mm pitch, through-hole mounting, solder termination, and latch holder fastening. The MDF6-18DP-3.5DSA(23) is the active equivalent.

Q: What is the difference between the contact finishes?

A: The MDF6-18DP-3.5DSA(05) uses Tin-Copper finish on the mating contact, while the MDF6-18DP-3.5DSA(23) uses Tin finish. Both finishes meet the 300V rating and operating temperature range of -30°C to 85°C.

Q: Are there packaging differences between these parts?

A: The MDF6-18DP-3.5DSA(05) packaging is not specified in available data. The MDF6-18DP-3.5DSA(23) is supplied in bag packaging.

Q: Do both parts meet RoHS requirements?

A: Yes. The MDF6-18DP-3.5DSA(05) is RoHS Compliant. The MDF6-18DP-3.5DSA(23) is ROHS3 Compliant, representing an updated regulatory classification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the contact length specifications identical?

A: Contact length - mating differs by 0.01mm (5.59mm versus 5.60mm), which is within normal manufacturing tolerance and does not affect functional compatibility. Contact length - post is identical at 0.138" (3.50mm).
